We hear a lot of rhetoric about strong border protection these days, but not much has been said about preserving the sanctity of the boundaries protecting America’s public parks. That’s a real shame, given new research that has mapped an alarming proximity between toxic waste sites across the U.S. and our nation’s otherwise scenic and beautiful public parks. But the scope of the problem is even worse when viewed in the context of the EPA’s broader category of Toxics Release Inventory (TRI) sites. And at least 63 of these parks currently share property with one of these toxic sites. “[The] greening of post-industrial landscapes, and the creation of recreational areas across time results in the layering of different types of space at a given location,” Noppert’s team wrote.
